In my opinion, the three models of Nieto - Comando, Poseidon and Carbitera - are excellent knifes, well thought out, at affordable budget. Each of them is sturdy and completely reliable working knife, at any environment, which is easy to maintain. Also, the workmanship is good and everything is matched and fitted properly. It should be noted that, perhaps to keep the cost low, the stainless steel liners (which are riveted to the frame) are left roughly machined (in the inner sides) and the blade runs without washers. However, in real use, I do not feel any serious lack of functionality, due to that. Moreover, the frame is so solid that the blade does not shift from centering and the disassembling/assembling is quite easy and simple. On the other hand, the steel on the blade is of high quality and it is machined precisely. The fit and finish of the G10-scales is fine.
About this concrete model (Poseidon) - sturdy knife with clean smooth lines, which is very comfortable to work with. The steel on the blade is N690co and performs really well (with very aggressive bite). The blade tip is well accessible and with the proper thickness for precise work. The handle ergonomics is nice. The balance point in unfolded position is at the position of the middle finger. The mechanics operates smoothly. In conclusion, I recommend this knife.
